Staff may ask you to stop impersonating them as it can be seen as disrespectful to copy their name. As for you all changing your name to Coolcat, if multiple people have the same name it makes it very difficult for individuals to be targeted in game, for example when someone wants to kos a Coolcat but there are several of them we have a problem. If you do change your name and someone takes your old one then that is your problem as you were the one who gave up that name in the first place, however he should not have been blackmailing you for it back. Someone correct me if i am wrong but i don't think the impersonation stuff even applies to a user impersonating another user, so in short i don't think you should have been punished.
